PKR president Anwar Ibrahim has warned that any party member which attempted to split the party or sabotage the party's upcoming national congress will be sacked.

Speaking to reporters at the Parliament lobby today, Anwar said his commitment was to unite the party while noting that more than 80 percent of party delegates had already registered for the congress, which begins tonight.

"Maybe only 10 percent won't turn up. I hope there is no (alternative meeting) because any leaders who attend it will be sacked," he said.
